PAUL J. OI-IASSAGNE, OF AKRON, OHIO.

SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 429,503, dated June 3,1890.

Application filed November 29, 1889- Serial No. 332,001. (No model.)

To all whom it may concern.-

Be it known that I, PAUL J. CHASSAGNE, of Akron, in the county of Summitand State of Ohio, have invented certain new and useful Improvements ina Combined Sash-Holder and Burglar-Alarm; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification.

My invention relates to an improvement in combined sash-holders andburglar-alarms; and it consists in the combination of the plate which issecured rigidly to the inside of the window-frame, a second plate whichis hinged to the lower end of the stationary plate, and aspring-actuated rod for the purpose of forcing the hinged plate againstthe'sash when it is raised, as will be more fully described hereinafter.i

The object of my invention is to provide a frictional device for holdingthe sash at any desired-elevation and thus do away with the weights,cords, and other similar devices which have heretofore been used forthis purpose.

Figure 1 is a side elevation of a windowframe to which my invention isapplied,-

partly in section. Fig. 2 is a vertical section taken at right angles toFig. l and showing the hinged plate in a raised position.

A represents an ordinary window-frame, to the inner side of which in theline of travel with the lower sash B is secured the plate 0, which isplaced in a suitable recess formed in the frame to receive it. Thisplate may be of any desired length and width, and has an opening throughit sufficiently large to let the spring-actuated operating-rod projectthrough. Hinged or pivoted in any suitable manner to the lower end ofthis plate O is a second plate D of about equal length, width, andthickness, and which when left free to move drops freely down over thetop of the lower'sash. When raised into a vertical po sition by theupward movement of the sash, this plate closes into the same recess inwhich the plate 0 is placed, and the two plates then just fill thisrecess, so as to leave the plate D flush with the inner side of thesash.

Extending through the frame at right angles to the two plates 0 D isasuitable opening, and in this opening is preferably placeda tube F, ofglass or any other suitable material. In this tube F is placed a rod G,which is operated by the spring 1. Either the rod may be provided with ashoulder against which the spring will bear and the inner end of the rodbe prevented from being forced out of the tube F by a washer placed uponit and a pin which passes through its rear end or any other suitableconstruction that may be preferred will be used; The outer end of thisspring-actuated rod G projects through the opening in the plate 0, andwhen the plate D is raised by the movement of the sash the plate bearsagainst the outer end of the rod G and forces it back into the opening.The pressure of the spring-actuated rod against the plate D causes theplate to exert a sufficient amount of frictional contact against thesash to hold it in any desired position and thus do away with the use ofthe Weights and cords and the boxes in the frame to receive the weightswhich have heretofore been used. The pressure of this plate D beingalways uniform against the sash, the sash can be left in any desiredposition after being raised without the slightest fear of its falling.

In case it is desired to use this device as a burglar-alarm, it is onlynecessary to connect one of the wires of the battery with the plate 0and the other wire with the spring-actuated rod G. This rod, beingplaced ina glass or non-conducting tube, does not come in contact witheither of the plates 0 or D until the plate D is raised by'the raisingof the sash B. As soon as the plate comes in contact with the end of therod the circuit is completed and the alarm is sounded.

In order to prevent the ringing of the alarm during the day, it willonly be necessary to place a piece of paper or other similarnonconducting material inside of the plate D, so as to prevent thecircuit from being completed.

If so desired, the hinged plate can be dis pensed with and acrescent-shaped or semicircular plate can be fastened to the end of andthe spring-actuated rod G, which has its the rod, so as to bear againstthe sash and outer end to bear against the inner side of the thussupport it in position. The stationary plate D and force it against theedge of the plate and the hinge can be made together in sash when thesash is raised, substantially as 15 5 a single piece. shown anddescribed.

Having thus described my invention, I In testimony whereof Iaifix mysignature in claim-- presence of two witnesses.

The combination of the stationary plate 0 PAUL J. CIIASSAGNE. and thepivoted plate D, which is raised or \Vitncsses: IO closed by the upwardmovement of the sash, I 0. L. SADLER,

with the tube which is placed in the frame, I 'l. E. W'ELLS.
